I was ruminating on this topic the other day. The seven mainline denoms (ABCUSA, Disciples, ELCA, UMC, PCUSA, TEC, UCC) have been forgone conclusions for some time. The REAL problem is the encroachment of similar thinking into the broad evangelical churches.
My seminary days (back when buggies were the norm? in the mid '70s) saw the publication of Paul Jewett's Man as Male and Female, arguing that Paul was "wrong" in 1 Tim 2 and that we did not need to feel constrained by his errors.
Having "heard it all" in Pasadena in a "leading indicator" seminary for progressive trends among evangelicals, it has not surprised me to watch the spread of the ideology. But, the rationalistic tendency of "progressive" evangelicals to "explain away" clear texts of Scripture because they run counter to the current Zeitgeist is a two edged sword with some pretty unacceptable consequences. It results in untethering doctrine from the source of doctrine in a way that allows for pretty much anything to be defended as acceptable.
You know, the examples of women exercising public roles in both testaments do not necessarily contradict the explicit instructions by Paul regarding church order in 1 Cor (yes I accept the text as legitimate) and 1 Timothy. The complementarian view might not be easy to implement or be in sync with the culture, but the hermeneutic being promulgated by so many evangelicals I hear these days will likely result in the vitiation of a number of core Christian doctrines over the next decades.
Besides, the whole "has God really said" type of argument ended rather badly in Gen 3. I do not expect it to fare any better today.
